ANTISLIPPING TIRE-COVER.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application led August 1.9, 1907. Serial N o. 389,209.

To all whom it may concern:

Be it known that I, ISAAC J. D. FAIR- HURs'r, .a citizen ofthe United States, residing at Orfordville, in the county of Rock and State of Wisconsin,have invented certain new and usefullmprovements in Antislipping Tire-Covers; and I do declare the folowing to b e a full, clear, and exact description'of the" invention, such as Will enable others skilled in the art to which it appertains to make anduse the same.

for automobiles or other ve readily v This invention has relation to new and useflil improvements in anti-slip ing tire covers fiicle tires, and has for its object to provide a simple and durable tire cover adapted to be easily and appliedin position, throu h the use of which skidding or slipping of ve Iicles may arrangement of deseri lis be eliminated.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and parts as will be more fully ed and particularly pointed out in the ap ended claim.

n the -accompanying drawings,-Figure a top plan view of a portion of a tire cover constructed in accordance with the invention applied to a corresponding portion of a tire; Big. 2 is a longitudinal vsectional view cut on the line 2-2 of Fig. l; and Fig. 3 is a cross section of Fig. 1'.

Referring to the drawings for a more particular description of the invention, the numeral 1 indicates a tire of any suitable form.

In carrying out the invention, a cover 2 of leather, rawhide or other suitable material having a sufficient flexibility, is positioned or arranged over the tire and is fastened or laced at its side edges thereto by flexible strings 3. 4

In lacing the cover to the tire, the stitches may be arranged in any suitable manner and be of any suitable length or lengths, as is found most desirable in the application of the invention. A. 'flexible strip 4 of leather, rawhide, or other suitable material is also arranged over the tread portion of the tire under the cover, and cooperates with the cover to form a securing means for the anti-skidding devices. These devices are arranged over the cover and comprise inner or base plates 5 of hexagonal crm, with central preferably circular openings or apertures 6,

and are arranged in contiguous relation to ,im

l cover the tread portion of the cover. Outer plates 7, constituting burs, having central circular depressions or recesses 8 formed in their outer faces and corresponding outwardly extending portions 9 on their inner or under faces adapted to seat or t in the o enings or aperturesof the inner or base p ates 45,1are arranged over said plates. Said outer plates are also provided with central transverse apertures or perforations 1'0, the purpose of which will be disclosed. To fasten said flexible strip 4 and plates 5 and 7, respectively in position to the cover, rivets or fastening Inembers are arranged to work through said flexible stri and cover and through the apertures in sai' plates. The bases of these rivets or fastening members are'somewhat enlarged to securely, yengage or embrace the under surfaces or flacos ofthe flexible strip, while the outer or op )osito ends of the rivets engage the outer plates and project a suitable distance beyond the same, said projecting portions constituting spurs to coaet with the vplates in preventing skidding or slipping of the vehicle to which my improved tire cover Inay be a plied.v i

It is to, e particularly noted that by forming recesses or depressions in the outer plates 7 the rivets or fastening members could not after said plates ave become worn below said recesses.

From the foregoing description, taken in connection with tl Ie accompanying drawings, the construction and operation of the invention will be readily understood without ref quiring a more extended explanation.

Various changes in the form, proportion resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having described my invention, I claim 1* In combination with a tire, a flexible cover ranged over the tread portion of the tire under the cover, centrally aperturcd base plates arranged over the tread portion ofthe Correr. outer plates formed with centrally al 'ettured recessed portions arranged over 'tie Base plates with their recessed portions extending into the apertures thereof to points flush with the inner faces of the sameand instelling rivets extending through the and the minor details of construction may be 11 are employed and by any possibilitI become loosened until arranged over the same; a flexible' strip arexible strip, lthe tire cover and through the apertures of the base and outer plates, resneetvely, the outer ends of the rivets being s ightly enlarged to engage the recessed p0r- 5 tions of the outer plates and projecting beyoud the same.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
